LOOSE-LEAF BINDER COVER.

Application filed November 2, 1925.

This invention relates to loose-leaf binders of the type wherein a cover board is enveloped by suitable cover material and the same is then hingedly connected to a normally rigid member of the binder.

t is the primary object of the present invention to provide a new method of making loose-leaf binders, as well as to set forth a novel construction which permits of manufacturing the same at a saving of time and labor, and it will also be shown wherein a. binder assembled in accordance with this invention may be made at a great reduction in manufacturing costs.

An even further object of this invention is the provision of a method of making looseleaf binders which renders the same neater and more appealing to the eye of the purchaser and, therefore, more readily sold.

Other objects will appear during the course of the detailed specification which will clearly set forth the steps preferably used in making a binder in conformity with this invention and which is illustrated in the accompanying` drawing, wherein:

Figure 1 is a perspective view of a looseleaf binder made in accordance with this invention.

Fig. 2 is an enlarged, fragmentary detail section taken on line II-II of F ig. 1.

Fig. 3 is a stretchout view of the binder cover and parts, and,

Fig. e is a fragmentary plan view showing the exposed portion of the binder hinge pin and the hinge member which engages the same.

It is known that a substantially U-shaped channel is used in gripping the cover board before it is covered with the desired material, and that thel hinge pin and engaging'v member is used in practically the same manner as illustrated in thev drawing, and it is also understood that cover material is used to completely cover the channel and board after the channel has been pressed into place.

The present method of constructing the binder is expensive in that much hand work must be done in cutting away that portion of the covering material which falls over the hinge notch and pin. This cut-out lip must be pushed through the ope-ning behind the hinge pin and pressed into place on the other side of the cover, all of which consumes time and adds to the cost of manufacture.

Serial No. 66,239.

The method of making' and assembling a loose-leaf binder in accordance with this invention will permit of a reduction in the outhand work is eliminated.

In the drawing, the numeral 5 designates the tubular sheet engaging member of a binder, which carries a pair of hinge portions or members 6, used in liingedly supporting the binder cover'. y Y

1n making the binder cover, a flat body member 7 of suitable size should be provided and completely covered or enveloped with covering material 8 such as canvas or imitation leather. This material 8 may be glued or cemented tightly to member Tand allowed to thoroughly dry, after which a pair of notches 9 are punched or cut out of the edge to be hingedly connected. Both the body member and covering should be cut, clean and the notch formed in step fashion as shown in Fig. 3 to provide a portion for hinge pin 10. The pin 10 should now be positioned in the wider portion between edges 12 and the U-haped channel lslipped over the edge to further hold pin in place.

This channel 18 is preferably of heavy sheet metal and has its edges turned inwardly to grip both covering 8 and body member 7 when the walls thereof are pressed toward each other.

Channel 18 is ofI such weight and thickput cost, inasmuch as the above-mentioned ness that it will hold its gripping position after .the walls have been tightly pressed together. After channel 13 is secured in place, the hinge portion 6 of the member 5 is inserted in the space behind the hing-e pin 10 and curled about the same kby engaging that part of pin 10 exposed by notch 14, cut in the U-shaped member 13 at points spacedv apart to conform to the spacing of notches 9. The binder is now ready for use.

By placing channel 13 after covering 8 has been glued to body 7 the same is exposed tolview and presents a visible reinforcing for the hinged end of the cover. No frayed edges of covering .are present, and in iinish not heretofore used is given the binder without additional expense and with a lowering of manufacturing cost.

After the body member 7 is once covered, no additional gluing is necessary and no cuttingv of the covering material is required. The steps of performing the work are in the sequence as set forth herein, and the lll) neivmethod of constructing the binder has been made clear throughout the specification. Y

The invention is not limited to the structure shown .and described, as many modifications within the scope of the appended claims, may be made without departing from the spirit of the invention.

TWhat I claim isz l. L book cover comprising a body mein bei7 a U-shaped channel member with a notch cut out of the bight thereoi;l engaged with one edge of said cover, notches formed in said edge o said body member behind thenotches oi said channel and hinge pins mounted in said body member notches.

2. na loose-leaf binder, a sheet engaging member, a cover comprising a body member hinged to said engaging member, a U-shaped channel with a notch cut out of the bight thereof embracing one edge of said cover, notches formed in the gripped edge of said cover behind the notches of said channel, hing-e pins mounted in said cover body inember notches and hinge members carried by Y said .sheet engaging'member engaging said hinge pins.

3. In a loose-leaf binder, a hinged cover comprising a flat body member, cover mate rial enveloping said member, a U-shaped channel with a notch cut out of the bight thereo' engaged with the hinged edge of` the enveloped body member between its walls, notches formed in said body member behind Vthe notches of said channel and hinge pins mounted in said body member notches whereby the cover material is disposed between the body member and channel along said edge and hinge pins are eX- posed to be engaged.

il. ln a loose-leaf binder, .a cover coinprsing a 'fiat body member completely enveloped by cover material and having notches in one edge thereof, hinge pins positioned in said notches and a metal Uehapcd channel gripping the notched edge of said enveloped body member between its walls and having netches cut out of the liight thereoic to enpose a portion of said liine'e pins, said channel being placed over the cover material or' said cover whereby the hinged edge of the saine is visibly reinforced with metal,

ln testimony whereof l. hereunto aiix my signature.
